A friend's husband just got a call from someone claiming to be from the Internal Revenue. (The Income Tax people). The party claimed he owed the IRS $30,000 in back taxes, and should pay immediately or face fines. He thought it was hinky, and it was. The IRS doesn't let you pay over the phone, and they send letters, not phone calls. Happily, he called the real Internal Revenue, to be sure. But there are plenty of scammers out there.
